Design of STEM-based learning devices in direct current circuit section

Abstract

This study aims to design learning tools developed based on STEM (science, technology, engineering, and mathematics). The learning tools are learning media in the form of Virtual Laboratories (VLAB) and Student Worksheets. Physics learning presented is limited only to the direct current series. VLAB components are the starting page, instructions for use, brief material on direct current circuit, direct-current circuit practicum using PhET interactive simulations equipped with worksheets, innovative videos for making flashlights and evaluations in the form of multiple-choice questions. The student worksheet section consists of two student worksheets, the first is a scientific worksheet that completes practicum activities in VLAB, and the second is an engineering worksheet in the form of student project worksheets to be able to create an innovative flashlight. The learning kit is measured through a validation process. VLAB is validated by 3 experts namely 2 content experts and 1 media expert. Student worksheets are validated by 3 experts, 2 content experts, and 1 language expert. The results of this study indicate that STEM-based learning tools namely VLAB and Worksheets are valid and can be applied in learning.
